Installing shared assemblies to the GAC

Hi,

I am working on a Basic MSI project and I am currently playing around with the GAC.


  • I have 1 InstallShield project that produces 2 releases (ReleaseA and ReleaseB) for 2 different product (ProductA and ProductB).
  • I have split 2 release specific features, and one common feature

    • FeatureA (ReleaseFlag: ReleaseA)
    • FeatureB (ReleaseFlag: ReleaseB)
    • FeatureCommon (No ReleaseFlag)

  • I have one .NET assembly that is shared by the 2 products.
It looks like a typical scenario for an assembly installation to the GAC.

Here are my questions:

  • Shall I make only 1 component, and include it in FeatureCommon? Or shall I make 2 components (ComponentA and ComponentB), and assign them to FeatureA and FeatureB respectively?
  • If I make 2 components, shall they have the same Component Code?
  • Shall I set the component as "Shared", or will the GAC handle the reference counting by itself?


Thanks in advance for your help!
Regards

Please make sure your assemblies are strongly named. That is the essential part.

•Shall I make only 1 component, and include it in FeatureCommon? Or shall I make 2 components (ComponentA and ComponentB), and assign them to FeatureA and FeatureB respectively?

Because the products share the assembly, I would have included it in the FeatureCommon.

•If I make 2 components, shall they have the same Component Code?

Yes.

•Shall I set the component as "Shared", or will the GAC handle the reference counting by itself?

You do not have to mark it as shared. GAC handles the sharing part.
